CVE-2025-62156Public exploitNetwork attack vector

Container file overwrite via unchecked archive paths

Published Oct 14, 2025 · Updated Oct 14, 2025

Path traversal in Argo Project Argo Workflows before 3.6.12 and 3.7.0 through 3.7.2 allows remote authenticated users to write files. The untar logic passes a cleaned, attacker-controlled archive entry to filepath.Join without verifying that the result remains under /work/tmp. Workflow-submission privileges are required, and successful exploitation can overwrite container configuration files for persistence or privilege escalation.
